Benefits of technology

The present invention relates to an RFID apparatus and a method for identifying and controlling RFID sensors. The apparatus includes an RFID reader, a microprocessor, and a converter for converting digital signals to analog signals. The apparatus can be enclosed in a housing and connected to control systems or other external devices through electrical wires. The method involves identifying RFID sensors and receiving digital signals related to physical parameters. The sensor type is determined and the signals are converted to analog signals within the apparatus and directed to the control system. The invention provides a flexible and efficient way to control RFID sensors and measure physical parameters.

Problems solved by technology

In these applications, special RFID tags are placed on books and expensive tools.

Embodiment Construction

[0023]Initially, this disclosure is by way of example only, not by limitation. Thus, although the instrumentalities described herein are for the convenience of explanation, shown and described with respect to exemplary embodiments, it will be appreciated that the principles herein may be applied equally to various RFID sensors operating in a variety of environments that can, in certain embodiments, be used with analog input control systems, for example. In what follows, similar or identical structures may be identified using identical callouts.

[0024]Embodiments of the present invention are generally directed to receiving digital RFID numbers and digital sensor readings associated with the digital RFID numbers and converting the digital sensor readings to analog values, which are transmitted along wire lines that correspond to the digital RFID numbers. Among other things, this solves a long-standing problem of sending multiple RFID sensor tag data along with an RFID number in an anal...

Abstract

An RFID apparatus is disclosed generally comprising an RFID reader antenna attached to a microprocessor, the RFID reader antenna adapted to receive a first digital signal from a first RFID sensor and a second digital signal from a second RFID sensor. The RFID apparatus further possesses a converter that converts the first digital signal to a first analog output, such as electrical current, and the second digital signal to a second analog output. The apparatus can further possess a first electrical wire adapted carry the first analog output to a control system when the first electrical wire is connected to the control system. Also the apparatus can possess a second electrical wire adapted to carry the second analog output to the control system when the second electrical wire is connected to the control system. The control system is external to RFID apparatus and independent of the RFID apparatus.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a non-provisional application which claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 62 / 297,289, entitled RFID READER FOR RFID SENSORS filed Feb. 19, 2016, the entire disclosure of which is hereby incorporated by reference.FIELD OF THE INVENTION[0002]The present invention relates generally to a system and method of converting and directing multiple digital RFID sensor signals to analogue values and digital values along a plurality of pathways.DESCRIPTION OF RELATED ART[0003]Radio Frequency IDentification (RFID) systems are used in libraries and retail stores, like Home Depot. In these applications, special RFID tags are placed on books and expensive tools. When the book or tool passes by an RFID reader, the identification of the book or tool is read by the reader using radio waves. One unique aspect of RFID technology is that an identification number can be transmitted wirelessly using...
